BACKGROUND: Predictors of worsening renal function (WRF: increase in serum creatinine ≥0.3 mg/dl from the value on admission) in patients with acute decompensated heart failure (ADHF) treated by low-dose carperitide (0.01-0.05 μg/kg/min) are unclear.Methods and Results:We retrospectively investigated predictors of WRF within the first 24 h of low-dose carperitide therapy in 205 patients (mean age, 75.6±12.1 years) hospitalized for ADHF and treated with low-dose carperitide between January 2006 and April 2014. WRF occurred in 14 patients (7%). A multivariate adjustment analysis showed that independent predictors of WRF within 24 h were hypotension (systolic blood pressure <90 mmHg) within 12 h (odds ratio, 8.7; 95% confidence interval, 2.38-35.88; P=0.0012) and serum creatinine on admission (odds ratio, 3.64; 95% confidence interval, 1.84-7.67; P=0.0003). In patients with estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m(2), the rate of WRF occurrence was higher in those complicated by hypotension than in those without hypotension (22.6% [7/31 patients] vs. 4.4% [5/113 patients], P=0.0041). In contrast, in patients with eGFR ≥60 ml/min/1.73 m(2), hypotension did not influence the occurrence of WRF (0% [0/9 patients] vs. 3.9% [2/51 patients], P=NS).
CONCLUSIONS: Hypotension within 12 h and renal dysfunction on admission are independent predictors of WRF within 24 h in patients with ADHF treated by low-dose carperitide. Hypotension may not cause WRF in patients with eGFR ≥60 ml/min/1.73 m(2).
